black hole accretion disk

Active galaxies give off bright radiation from their cores, where gas heats up as it is compressed into a swirling accretion disk encircling the black hole.

活动星系从它们的核部发出明亮的光芒，在那里，气体被加热并压缩成一个漩涡状的圆盘，漩涡的中心便是黑洞。

We'd be able to connect a lot of the physics happening within the gaseous environment and accretion disk to the binary black hole merger to the gravitational radiation.

我们可以将很多发生在黑洞对合并时的气体环境和吸积盘里的物理过程与引力辐射联系起来。

Infalling gas may first collide not only with itself but with an accretion disk of swirling material surrounding the black hole.

正在下落的气体不但会先和自身发生碰撞，还会和黑洞周围盘旋着的物质吸积盘相互碰撞。
